Summary:

Social surveys were the starting point for research in Nang Rong, a district in the Buriram province of northeast Thailand. The surveys were part of three waves of data collection conducted in 1984, 1994, and 2000. The baseline was established in 1984 when a community survey and a household census were conducted in 51 study villages. The census obtained information on all members of all households within the study area. A second round of surveys was fielded a decade after the baseline, in 1994, ... (more info)

Social surveys were the starting point for research in Nang Rong, a district in the Buriram province of northeast Thailand. The surveys were part of three waves of data collection conducted in 1984, 1994, and 2000. The baseline was established in 1984 when a community survey and a household census were conducted in 51 study villages. The census obtained information on all members of all households within the study area. A second round of surveys was fielded a decade after the baseline, in 1994, building on and extending the original research design and focus. The 1994 data were collected through a community survey administered in all villages in Nang Rong (including but not limited to the original 51 study villages), a household survey providing a complete census of all households in each of the original 51 study villages, and a migrant follow-up survey. The migrant follow-up survey collected data on out-migrants from 22 of the original 51 study villages who had relocated to one of four urban destinations: (1) metropolitan Bangkok, (2) the eastern seaboard, a focus of rapid growth and development, (3) Korat, a regional city, and (4) Buriram, the provincial capital. The 2000 round of data collection again built on the previous data collection efforts and included a community survey administered in all villages in Nang Rong district, a household survey and complete census of the original 51 study villages, a migrant follow-up survey that tracked out-migrants from 22 villages to the four urban destinations as well as to rural villages within Nang Rong district. In addition, this round also included a geospatial component with the collection of locational data for dwelling units and agricultural plots.

Dataset(s)

WARNING: This study is over 150MB in size and may take several minutes to download on a typical internet connection.

The restricted-use data initially included four datasets that were intended to serve as linking files between the public and restricted versions of the data. However, the linking variables were merged into the appropriate restricted datasets and the linking files were eliminated.

Methodology

Sample:
For the 1984 data purposive sampling was used to select villages. Group discussion method with selected village informants was employed to collect village information. This yielded a sample of 34,035 people living in 5,860 households in 51 villages in Nang Rong district. For the 1994 data sampling consisted of a community profile, household survey, and a migrant follow-up survey. The 1994 community profile gathered information in all 310 villages in Nang Rong district, including but not limited to the 51 villages that were part of the original 1984 survey. The 1994 household survey was a complete household census in each of the 51 villages that were part of the 1984 survey. The 1995 migrant follow-up survey collected data from 1781 out-migrants from 22 of the 51 villages. The 22 villages were selected randomly within strata created by cross-classifying general location and distance from major paved roads in 1984. Persons resident in 1984 but no longer resident in 1994 were candidates for follow-up if they had gone to one of the four most popular destination areas: Bangkok, the eastern seaboard, Korat, or Buriram. For the 2000 data sampling consisted of a community survey profile, household survey, and a migrant follow-up survey. The 2000 community survey profiled all 346 villages in Nang Rong district. The 2000 household survey included a complete census of all person in all households in the 51 original study villages. The data include persons who migrated into the study villages as well as those 1984 residents still residing in those villages. The 2000 survey included a follow-up on all 1984 and 1994 residents in 2000. An annual life history was collected in 2000 for those aged 18-41. The 2000 migrant follow-up survey tracked more than 3,400 migrants from 22 villages to the four urban destinations and to rural villages within Nang Rong district.

Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:
